Design your own programming language and its compiler part 1

Aspiring software engineers and systems architects looking to demystify the inner workings of compilers and interpreters will find this course by Tylor Chen incredibly rewarding. Instead of focusing solely on dry, theoretical parsing concepts, the curriculum takes a highly practical, test-driven approach (TDD) using widely-adopted technologies like JavaScript and React. Students will journey from the absolute basics of language design to building a fully functional interpreter from scratch. This includes implementing crucial stages such as lexing (tokenization), parsing, and evaluation. What sets this course apart is its emphasis on developer tooling; learners will construct a complete Read-Eval-Print Loop (REPL) and an interactive debugging IDE right inside a web application. Beyond basic syntax processing, the lessons cover advanced computer science paradigms like lexical closures, scope management, and object-oriented class inheritance. This course is ideal for intermediate programmers who want to transition from simply consuming programming languages to actively creating them, thereby gaining a profound competitive edge in software engineering, tooling development, and syntax optimization.
